Title: Optical cable system and its storing method
Inventor: TANIMURA KATSUHIKO
IPC: H04B10/25
Filed: 1987-11-20
Abstract: PURPOSE:To prevent a voltage which breaks a repeater from being generated even if a hit is caused during a test by connecting optical cables which have an S-twisted and a Z-twisted tensile strength body to both sides of the repeater by turns. CONSTITUTION:When a signal is repeated by connecting optical cables S1, S2, Z1... by using repeaters A1, A2, A3..., the optical cable S1 which as the S-twisted (clockwise) tensile strength body is connected to the connection part 11 of the repeater A1. The Z-twisted (counterclockwise) optical cable Z1 is connected to the connection part 13 of the repeater A2. Consequently, the S- twisted and Z-twisted optical cables are arranged alternately in each section sandwiched between repeaters. Consequently, even if a hit occurs during a feeding test, the induced voltage is reverse in inductance in each section, so the voltages of adjacent sections cancel each other, thereby preventing generation of a voltage which breaks a repeater.
